Secret Files

There are 9 Secret Files in the game and they reveal the origins of the plague.

Flooded Jungle - 3 Files

Biosphere Laboratory - 1 File

Tunnel - 1 File

Henderson - 4 Files

One of the files can only be reached after getting (or completing) the White Line side quest from Bruce in Halai Village.

Secret Files 1 -- In Halai Village, there is a small bedroom on the ground floor of the trader's building that has a hoo-doo shrine with Oleander scattered around. The file is under the bed in that room.

Secret Files 2 -- In Halai Village, the shack where Father Marcus tells you to go in Where The Dead Live. It is next to the Liquid Fire mod.

Secret Files 3 -- In the drug lab in the middle of the flooded jungle for the side mission White Line (east of Hanging Joe's and south of Peter Spicer's Shack). It will be to the west of the Treehouse Maggie asks you to check first in Safe Haven. Getting the boat isn't required, but makes the trip much faster.

Secret Files 4 -- In Dr. Kessler's Biosphere, check the hallway between the office and the shower/decontamination room for this file.

Secret Files 5 -- The Tunnels' Smuggler Den. Check the Chief's quarters for this file ... it's next to one of the bunking mattresses.

Secret Files 6 -- The military base west of the cinema. The files are in the outpost's comm building -- in the room where you battle the second Grenadier in a series of small office rooms. There is a large comm panel in that room as well as the Rifle Ammo blueprint.

Secret Files 7 -- The military base west of the cinema. The files are next to the fast-travel map, on the table with the shotgun spawn.

Secret Files 8 is on the port side of the crashed chopper (in Chapter 11) at the Old Fort of Henderson. Check the seats next to the mini-gun pylon.

Secret Files 9 -- The workbench at the last part of Henderson's QZ, atop the stairs from the Docks portal, there's a secret file in the boxes near the workbench.
